To-aZZ whom t may con/0cm:

Be it known that I, STANLEY R. DE PUE, a citizenof the United States ofAmerica, and a resident of the city' ofv Washington, DistrictofColumbia, have invented certain new and useful Im rovements inCompactible'Typewritingachines, ofwhich the followingis a full and clearspecification.

The Object of this invention is to so construct the machine that it maybe compacted for convenience in transportation and storage, as morefully'hereinafter set forth.

In the drawing is vrepresented a vertical, longitudinal, sectional viewillustrating so much of a typewriting'machine as is neces-l toillustrate my present improvement. eferring vto the drawing annexed bynumerals, 10 designates the mainv frame, on which are mounted injanysuitable manner the key-bars 11, each key-bar being provided Sal vwithadepending ear 12 which is provided with a pin 13 in its lower end,which engages the radialslot 14 in arm 15 journaled on a rock shaft l'16affixed to the lower edges of the side-bars of the frame# Each of thearms 15 is provided with an upstanding larm 17 which is connected by arearwardly-- extendinv link 18l to the heel of the typebar 18 o theusual construction. The typebars are pivotally mounted in the usualmanner in the type-bar Asegment 19. This manner of connecting 'thekey-bars to theA type-bars is advantageous in that it enables thetype-bar segment to be brought well forward vin the machine in order toprovide space enough between the type-bar segment and the rear wall ofthe frame to receive the platen carriage and connected parts when themachine is compacted, as more Afully hereinafter set forth.

At each side of the main frame is pro- 4 vided a pair of vertical guideribs 20 which are engaged by channeled legs 21 of a top plate or frame22 which carries the-usual platen carriage 23. This frame or plate 22 isthus vmade vertically slidable, and it is held in its adjusted positionsin'any suitable manner, vpreferably vby spring-actuated latches 24, oneof which'is mounted in each of the legs 21 and'is adapted to engagenotches 25 in the guide ribs 20, the en age-l ment ofthe latches withthe notches eing preferably a frictional one, s o that the movable framemay be raised or lowered -by aplie behin 'plying a little effort theretoland also in order that, whether the frame be lifted or lowered, it willautomatically lock at the desired height. The'lower notches 25 are solocated that `when they are engaged by the latches, the rear portion ofthe movable frame together with the platen carriage will anism carriedby the movable yframe will have been lowered to al point approximatelyon a level with 'the upper ends of the guides 20, thus compacting themachine to the eX- tent of movement of. the frame upon the guides. Theforegoin construction is more ullyillustrated and,- escribed in myapplication filedvk herewith, serially numbered 178,252. j

Depending centrally in the type-bar segment isa universal bar 26 whichis adapted to be centrally struck by a projection 27 on each of thetype-bars. Pivotally mounted on the depending hanger 28 carried by theplaten carriage supporting frame '22 is an escapement lever 29 whichnormally bears against the universalv bar 26 and controls the escapementwheelv 30 in the usual.manner, the shaft of this escapement wheel beingsupported from the frame 22 and being provided with a pinion- 31 whichengages the feed-rack 32 on the carriage. The usual spring, not shown,is provided for moving the carria e, and any suitable ribbon-feeding andvi rating means, operable from the universal bar 26, may be mounted onthe supplemental frame, so as to be vertically adjustable therewith. `Itwill be observed that all the carriage-feeding devices are mounted onthe supplemental frame, so that Awhen this frameis dropped down into thelIt will be observed further that by pivotingthe rocking members 15 onan axis below the key-levers, `I am enabled to bring the the typesegment while the mech Specification of Letters Patent. v i PatentedOct, 26, 1920.-

type-bars closer to thev key-levers and thus obtain desirablecompactness in a verticall direction.

It will be understood that the case shift may be obtained either byshifting the supplemental frame up and down in addition to the shiftingthis frame receives in compacting and extending the machine, or the caseshift may be obtained by vertically shifting the type-bar segment; Ipreferl the latter, as fully disclosed in my co-pendingapplication filedherewith.

It will be observed that by continuing the pull upwardly on thesupplemental frame 22, this frame together with all the parts connectedthereto may be entirely separated from the base-frame; the advantage inthis is that it will give ready access to all the mechanisms carried byboth the base-frame and the supplemental frame, to thereby greatlyconvenience the matter of cleaning and repairingA the parts.

The nature and scope of the invention having been thus indicated and itspreerred embodiment having been specifically described, what is claimedas new is:

l. In a collapsible typewriter, a baseframe carrying the printinginstrumentalities, a supplemental-frame carrying the platen carriage andescapement mechanism, and means whereby this supplemental-:trarnetogether with said escapement mechanism the combination of a base frame,a type seg,

and platencarriage may be, as an entirety, slidably separated from thebase frame.

2. In a collapsible typewriting machine, the combination vof a baseframe, a typel bar action mounted on the base frame, a universal barmounted on the base frame and op-v erable by the type bars, a platencarriage, a carriage support, connections between said support and thebase frame whereby said support 'may be shifted relatively to the baseframe to place the carriage in a lower upright position at the rear ofthe type bar action to reduce the height of the machine when not in use,and carriage feeding mechanism operable by the universal bar and movableas an entirety with thecarriage and carriage support relatively to theuniversal bar 4to a lower position out of coi operative relation withthe universal bar when the machine is collapsed.

3. In a collaps1ble typewriting machine,

mentl mounted on the base frame, type bars pivotally mounted on saidsegment, lrey` levers mountedon the base frame and operatively connectedto actuate the type bars, a universal'bar supported on the type segmentwithin the are of the segment and operable by the type bars, a platencarriage, a carriage support, .connections between said support and thebase frame whereby said supportv may be shifted relatively to the baseframe to place the carriage in a lower upright position at the rear ofthe type segment to reduce the height of the machine when not in use,and carriage feeding mech- Leaders anism operable by the universal barand movable as a unit in its entirety with the carriage and support to alower position out of coperative relation with the universal bar whenthe machine is collapsed.

4. In a collapsible typewriting machine, the combination of a baseframe, a supplemental frame, sliding connections between said frameswhereby the supplemental frame may be moved vertically up and down onthe base frame to collapse and extend the machine, a vuniversal bar, atype bar action mounted on the base frame, a platen carriage mounted onthe supplemental frame, and carriage-feeding mechanism operable by theuniversal bar and movable in its` entirety with the carriage andsupplemental frame to a lower position out of cooperative relation withthe universal bar,

5. In a collapsible typewriting machine, the combination of a baseframe, a supplemental frame, sliding connections between said frameswhereby the supplemental lframe may be moved vertically up and down onthe base frame to collapse and extend the machine, a type bar actionmounted on the base frame, a universal bar operable by the type bars andsupported within the base frame independently of the supplemental frame,a platend carriage mounted on the supplemental frame to move therewithin a vertical plane at the rear of the type bars and universal bar, andcarriage-feeding mechanism locatedbelow the carriage and mounted ltomove in its entirety vertically 100 with the carriage and supplementalframe into and out of coperative relation with the universal bar. v

6. rIhe combination' with a base-frame carrying printinginstrumentalities and an 105 upright universa bar, of asupplementalframe rectilinearly slidable to a point behind saiduniversal bar for compactness, said supplemental-frame carrying aplaten' carriage and a complete escapement mecha- 11C nism, theconstruction beingsuch that when the supplemental-frame is slid up tooperative position the operating elements-.of the escapement mechanismwill be -moved into position to be operated by the universal bar. 11E

7. Ina collapsible typewriter, a baseframe carr ing the type-bars andthe. operating mec anism thereof, and a supplemental frame carrying theplaten carriage and the carriage-feed mechanism, said sup- 12( plementalframe being vertically slidable upon the base-frame and readilydetachable therefrom as`an entirety and by a vertical sliding action. l

8.' The combination of a base-trame car- 12! rying printinginstrumentalities, including an. upright segment carrying a dependinguniversal bar, a supplementalframe carrying the complete escapementmechanism and the platen carriage, means whereby this supple- 13mental-frame is sldable rectilinearly dovvn behind'the universal bar to.obtain compactness.

9. The' combination with a base-frame 5 carrying printinginstrumentalities, including a segment and a universal bar, of asupplemental-frame slidable rectilinearly down behind the segment forcompactness, said supplemental-frame carrying a platen carriage and acomplete escapement mechanism, the latter depending from thesupplemental-frame to bring its operating elements into operativerelation with the universal lbar when the supplemental-frame 'is in its.extended or loperative position.
